HD66765 396-channel Segment Driver

peThe HD66765, 396-channel segment driver LSI, displays 132RGB-by-176-dot graphics on STN Sdisplays in 4096 colors. It is for driving STN color LCD displays to a maximum of 132RGB by 176 ydots, in combination with the HD66764 common driver. The HD66765’s bit-operation functions, 16rbit high-speed bus interface, and high-speed RAM-write functions enable effic.
